Answer:
12 in³
Step-by-step explanation:
Its made up of 12 (4×3 = 12) cubes of 1 in³ each
So 12 × 1 = 12 in³
Amare=x Jing=Y x=2y 42=x+Y (<-These are 2 base equations for systems of equations) 42=2y + Y 42=3y (Y=14) 42=x + 14 42-14=x (x=28) Amare=28 Jing=14
We can solve it by substitution: y = - 3 x - 1.
So the 2nd equation becomes:
4 x + 3 * ( - 3 x - 1 ) = 2
4 x - 9 x - 3 = 2
- 5 x = 2 + 3
- 5 x = 5
x = 5 : ( - 5 ) = - 1
y = - 3 * ( - 1 ) - 1 = 3 - 1 = 2
Answer: x = - 1, y = 2.
